Proximity sensor valve and lock system using same

摘要

A proximity sensor valve includes a housing which defines a fluid inlet and a fluid outlet in communication with a cavity. A plunger pin within the cavity for movement along an axis, the plunger pin movable between an extended position and a retracted position. The plunger pin extends at least partially outward of said housing at the fully extended position. A spool is within the cavity for movement along the same axis as the plunger pin, such that the spool and the plunger pin are movable with respect to each other to control fluid flow between the fluid inlet and the fluid outlet.

1. A fold system comprising:
a lock system that selectively locks a displaceable member in a folded position; and a proximity sensor valve in fluid communication with said lock system, said proximity sensor valve operable to control operation of said lock system in response to extension of a plunger pin from said proximity sensor valve, wherein said lock system includes a loch actuator positionable adjacent to a receptacle housed within said displaceable member that is to be locked, wherein said displaceable member to be locked is a rotor blade assembly of a rotary wing aircraft.
